Ukuba uthenga iimveliso ngenye yeekhonkco zethu, iBobVila.com kunye namaqabane ayo anokufumana iikhomishini.
Ukuba ugrumba imathiriyeli exinene kakhulu, umqhubi wakho wesuntswana eliqhelekileyo akanakuyisika.Izinto ezifana nekhonkrithi, iithayile, kunye nelitye zifuna amandla ongezelelweyo kwi-drill bit, kwaye noyena mqhubi unamandla kakhulu akanayo.Ezi ntlobo zeeprojekthi zifuna i-hammer drill egqwesileyo engenantambo, enokuthi inqumle kule miphezulu inzima.
Iibhithi ezingcono zombane ezingenazintambo zenza izinto ezimbini ngaxeshanye: zijikeleza isuntswana, kwaye ipinion kwisuntswana inyanzela ubunzima ukuya phambili kwaye ibethe umva wechuck.Amandla agqithiselwa kwincam ye bit drill.La mandla anceda i-drill bit ukuba inqumle amaqhekeza amancinci ekhonkrithi, ilitye okanye izitena, kunye nemijelo kwi-drill bit inokususa uthuli olwenziwe.Ezi ngcebiso zilandelayo zokukhetha eyona drill intle engenantambo iya kukunceda ufumane isixhobo esifanelekileyo seprojekthi yakho.
Nangona uninzi lwezona drill zibalaseleyo zinokwenza imisebenzi emibini yomqhubi wedrill eqhelekileyo, ayinguye wonke umntu.Nezona drill zincinci zincinci zineenxalenye ezinzima ngaphakathi, nto leyo ethetha ukuba zinzima ngakumbi kunezo drili zingenantambo.Bakwanayo ne-torque enkulu kunee-drill drill rigs, ke ukuba awuqhelananga nezixhobo zamandla, ungothuki ngamandla azo.
Ukuba awugrumbi kwikhonkrithi, izitena, amatye okanye i-masonry, akufuneki ufune i-hammer drill engenazintambo.Ungagcina imali ngokusebenzisa abaqhubi be-drill eziqhelekileyo kwiiprojekthi ezininzi.Nangona kunjalo, ukuba uzifumana udibanisa ikhonkrithi okanye ipeyinti rhoqo, unokucinga ukuba i-torque eyongezelelweyo enokubonelela ngesando iya kunceda ukukhawulezisa umsebenzi.
Ezi mpawu zilandelayo zenza ezinye iidrill zombane zivelele kwisihlwele.Ukuqonda ukuba ezi zixhobo zisebenza njani kuya kukunceda wenze isigqibo esinolwazi kwaye ubone ukuba ufuna enye yale mishini torque.
Izixhobo zehammer zisetyenziselwa ukugrumba imingxuma kwi-masonry.Amasuntswana okubhola asemgangathweni kunye neendawo zokubhola azifane zikrwele umphezulu weethayile, iindlela zokuhamba zekhonkrithi okanye iikhawuntara zamatye.Ezi zixhobo zixinene kakhulu kwimida yokusika i-drill bits eqhelekileyo.I-hammer drill exhotyiswe nge-masonry bit iya kungena ngokulula kwezi ndawo ezifanayo: umsebenzi wehamile uqhuba incam yesuntswana kumphezulu, uvelisa iitshiphusi zamatye okanye uthuli lwekhonkrithi, kunye nokucoca i-groove ye bit ukusuka emngxunyeni.
Khumbula, kufuneka usebenzise ii-masonry drills ukungena kule ndawo.Ezi drill zinamaphiko kwiingcebiso zokunceda ukususa uthuli, kwaye iimilo zazo zencam zahluke kancinane, zifana netshizili kunezoqheliso eziqhelekileyo.Ukongeza, ukuba unokungena kumphezulu wesixhobo sobumba, i-drill drill bit iya kuba buthuntu okanye iqhekeke ngokukhawuleza.Unokufumana i-masonry drills ukuba ithengwe ngokwahlukileyo kwiikiti ezinjalo.
Iimoto ezibhurashiweyo zithembele kwitekhnoloji “yesikolo esidala” ukuvelisa iimoto.Ezi njini zisebenzisa “iibrashi” ukunika amandla iikhoyili.Ikhoyili exhunywe kwi-shaft iqala ukujikeleza, ngaloo ndlela ivelisa amandla kunye ne-torque.Ngokubhekiselele kwimoto, umgangatho wayo wobugcisa uphantsi.
Itekhnoloji ye-brushless motor ihambele phambili kwaye isebenza ngakumbi.Basebenzisa izinzwa kunye neebhodi zokulawula ukuthumela okwangoku kwikhoyili, ebangela ukuba imagnethi ifakwe kwi-shaft ijikeleze.Xa kuthelekiswa nemoto ebrashiweyo, le ndlela ivelisa itorque enkulu kwaye isebenzisa amandla ebhetri amancinci.
Ukuba kufuneka ugrumbe imingxunya emininzi, ngoko ke ukuthenga i-brushless hammer drill kunokuba nexabiso leendleko ezongezelelweyo.Uqheliso lwehamile olubrashwayo lugqibezela umsebenzi ngexabiso eliphantsi, kodwa kunokuthatha ixesha elingakumbi.
Ngokuphathelele isantya, kufuneka ujonge i-drill enesantya esiphezulu se-RPM ye-2,000 okanye ngaphezulu.Nangona usenokungadingi isantya esiphezulu sokugrumba kwizinto ezibunjiweyo, esi santya sikuvumela ukuba uyisebenzise njengendawo yokubhoboza ngaphandle kokubhola ikhonkrithi kunye nezitena.
I-torque ikwabalulekile kuba ungasebenzisa i-hammer drill eyomeleleyo ukujija izikhonkwane ze-lag kunye nezikrufu kwizinto ezixineneyo ukulungisa iiankile zekhonkrithi, njl.Endaweni yoko, basebenzisa i-"unit wattage" okanye i-UWO, engumlinganiselo onzima wamandla e-drill bit on chuck.Ubuncinci i-700 UWO drill bits inokuhlangabezana uninzi lweenjongo zakho.
Okona kubaluleke kakhulu, abathengi be-hammer drill kufuneka babeke phambili ukubetha ngomzuzu okanye i-BPM.Le yunithi yokulinganisa ichaza inani lamaxesha i-hammer gear idibanisa i-chuck ngomzuzu.I-Hammer drills kunye ne-BPM ye-20,000 ukuya kwi-30,000 ifanelekile kwiimeko ezininzi zokugaya, nangona iimodeli ezinobunzima zinokunika i-RPM ephantsi ngokutshintshiselana nokunyusa i-torque.
Ngenxa yokuba i-hammer drill ivelisa i-torque eninzi okanye i-UWO, umsebenzisi ufuna indlela yokulungelelanisa ukuba ingakanani le torque ethunyelwa kwi-fastener.Ngaphambi kokuba ubambe i-fastener okanye i-screwdriver kwizinto eziphathekayo, i-torque egqithisileyo inokubangela ukuba iphuke.
Ukulawula ukuphuma kwe-torque, abavelisi basebenzisa ii-clutches ezihlengahlengiswayo kwiirigi zabo zokomba.Ukulungelelanisa i-clutch ngokuqhelekileyo kufuna ukukrazula ikhola phantsi kwe-chuck kwindawo echanekileyo, nangona isikhundla sihlala sihluka ukusuka kwisixhobo ukuya kwisixhobo kwaye kuxhomekeke kuhlobo lwezinto zokugaya.Ngokomzekelo, i-hardwoods enzima inokufuna izicwangciso eziphezulu ze-clutch (ngokude nje ukuba i-fasteners ikwazi ukuyiphatha), ngelixa i-softwoods efana nepine ifuna i-clutch encinci.
Phantse zonke izixhobo zokomba kunye noomatshini bokugaya (kubandakanya ukukhanya kunye nehamile ephakathi) zisebenzisa i-chucks yemihlathi emithathu.Xa ujikelezisa ii-chucks, ziyabamba kwindawo engqukuva okanye ene-hexagonal.I-chuck enemihlathi emithathu ikuvumela ukuba usebenzise iintlobo ezahlukeneyo ze-drill bits kunye neebits zomqhubi, yiyo loo nto ziphantse zijikeleze jikelele kubaqhubi be-drill.Zifumaneka kwi-1/2-intshi kunye ne-3/8-intshi ubukhulu, kunye nobukhulu obukhulu bunzima.
Isando esijikelezayo sisebenzisa i-SDS chuck.I-groove shank yezi drill inokutshixwa kwindawo.I-SDS yinto entsha eJamani, emele "Steck, Dreh, Sitz" okanye "Faka, Twist, Stay".Ezi zixhobo zokubhoboza zahlukile kuba isando sombane sibonelela ngomthamo omkhulu wamandla, ngoko ke indlela ekhuselekileyo iyafuneka ukuze kukhuselwe i-drill bit.
Iintlobo eziphambili zebhetri eziza nazo naziphi na izixhobo zamandla ezingenazintambo ziyi-nickel cadmium (NiCd) kunye ne-lithium ion (Li-ion).Iibhetri ze-lithium-ion zithatha indawo yeebhetri ze-nickel-cadmium ngenxa yokuba zisebenza kakuhle kwaye zinobomi obude benkonzo ngexesha lokusetyenziswa kunye nobomi babo benkonzo.Kananjalo zikhaphukhaphu kakhulu, ezinokuthi zibe ngumba wokuba sele urhuqa i-drill enzima yehamile.
Ubomi bebhetri ngexesha lokusetyenziswa budla ngokulinganiswa kwiiyure ze-ampere okanye i-Ah.Kwizixhobo zokomba ezikhanyayo, iibhetri ze-2.0Ah zingaphezulu ngokwaneleyo.Nangona kunjalo, xa ubetha i-masonry nzima, unokufuna ukuba ibhetri ihlale ixesha elide.Kule meko, khangela ibhetri ebekwe kwi-3.0Ah okanye ngaphezulu.
Ukuba kuyimfuneko, ibhetri enomlinganiselo weyure we-ampere ephezulu inokuthengwa ngokwahlukeneyo.Abanye abavelisi bathengisa iibhetri ukuya kuthi ga kwi-12Ah.
Xa uthenga eyona drill igqwesileyo engenantambo ehlangabezana neemfuno zakho, cinga ukuyisebenzisela iprojekthi.Le projekthi iya kuba ninzi yokwenza kunye nobukhulu kunye nobunzima be-hammer drill oyifunayo.
Ngokomzekelo, imingxuma yokugaya kwiithayile zodonga lwe-ceramic ayifuni i-torque eninzi, isantya okanye i-BPM.I-lightweight, i-compact, i-hammer ye-hammer bit inzima malunga neepounds ezi-2 (ngaphandle kwebhetri), inokusombulula ingxaki.Kwelinye icala, ukugrumba imingxunya emikhulu kwii-ankile zesakhiwo kwikhonkrithi kuya kufuna ii-hammer drills ezinkulu nezinzima, mhlawumbi neehamile zombane, ezinobunzima obufikelela kwi-8 pounds ngaphandle kweebhetri.
Kwizicelo ezininzi ze-DIY, i-hammer drill ephakathi lukhetho oluhle kuba inokusingatha iiprojekthi ezininzi.Nangona nceda ugcine engqondweni ukuba iya kuba nzima kakhulu kunomgangatho oqhelekileyo (udla ngokuphindwe kabini ubunzima), ngoko ke isenokungabi yinto efanelekileyo kuba iyona nto yodwa kwiworkshop yakho.
Ngolwazi lwangasemva lwe-cordless electric hammer drills, olu luhlu lulandelayo lweemveliso zokugrumba imingxuma kwizinto ezinzima lunokukunceda ukuba ufumane isixhobo esifanelekileyo kwiprojekthi yakho.
